In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: qcom: clear opened when stream enable fails
On enable, subs->opened is set before the service_interval is validated; an invalid interval jumps to the response label without clearing it, so the substream is wedged at -EBUSY until a disable or disconnect.
Clear subs->opened on the enable error path.
